Abstract
A high-density fermentation process for high yield production of a protein having swine growth hormone activity by transformant E. coli strains is described. The process employs transformant stains of E. coli containing a gene coding for a protein having swine growth hormone activity under the control of a bacteriophage lambda promoter-operator and a gene coding for the λc1857 temperature-sensitive repressor protein. In the initial growth period, the level of dissolved oxygen in the fermentation medium is maintained at about 20 % to 60 % of saturation and the temperature of the medium is maintained at a temperature at which the λ c1857 repressor protein is active. Production of the desired protein is then induced by raising the temperature of the medium to at least about 42°C. The temperature is then reduced to about 38°C to 41°C to optimize cell growth for the remainder of the induction period, during which the level of dissolved oxygen in the medium is maintained at about 10% to 40 % saturation, and the protein having swine growth hormone activity thus produced is recovered from the transformant cells.
